Navarro County · Corsicana (Shallow) field · Vertical
Mobil #16 (API 42-349-31961) is a former disposal or injection well in Navarro County, last operated by Contour Expl And Prod LLC; its UIC permit is no longer active.
The RRC has issued 2 drilling permits between 1981 and 1994, permitted to 1,050 ft.
It was permitted by Zsx, Inc. and has since transferred to Contour Expl And Prod LLC on the wellbore schedule.
Completion filings report 2 formation tops, including Midway, Nacatoch.
Its lease has reported 22.7K barrels of oil and 21 mcf of gas since January 1993, last reporting in July 2026. The lease carries 32 wells, so these are lease totals, not this well alone.
